Bike shop owner has not set the price yet... that was my Question...
to collect all the right parts, but it is hard to source the parts down south...
There are not many parts laying aroung from that era, 1 inch threaded HeadSet and have read that it need a "special" crankset or spindle, something like that?

Looks like a 19in. Maybe a 21 in. NO big deal, finding components for it. I can't see brake bosses but i don't think they had rollercams. BB is not that hard to find parts and deal w/it. Fork is the missing link really but a RS MAG 21 would fit nicely.

That's a nice frame. According to this source Mantis Bicycles you can read the serial # to be: model (XC) size (21) and production number (828) which I'm guessing would be around 1993/94. I don't think you'll find much problem finding parts for it, other then possibly BB spindles. The BB bearings are press fit, and readily available.

Go back and look for the fork. It will probably be chrome to match the rear end and it will be straight leg, tange dropouts and threaded steerer. Might have fender mounts on the rear of the dropouts as well.

Crazy paint job on that sucker. Brake levers and calipers are the right ones too!

You'll need to remove a circlip on each side where you can see the bearings. Then just give the spindle a few good whacks with a hammer. The spindle and 1 bearing should pop out. Then use a dowel or something similar inserted through the BB shell to knock out the other bearing.
